Access arrangements

The terms of an access arrangement need to support fair prices, quality services and choice. The access arrangement defines services to be delivered, service levels to be achieved and rates to be paid.

The Economic Regulation Authority (ERA) negotiates on behalf of the Western Australian community with Western Power before approving an access arrangement. Generally, it’s electricity retailers and generators such as Synergy who apply to gain access to the network, so they can transport electricity to customers.

On 28 February 2019, the ERA published its - decision for access arrangement four, the period 1 July 2017 to 30 June 2022.

We’ve now started preparing our fifth access arrangement, due on 1 February 2022 it will cover the five-year period from 1 July 2022 to 30 June 2027.

This is our opportunity to engage with the community to understand what energy services and solutions they value and need, now and into the future so we can revise the services we offer and update the prices we charge for these services.

The access arrangement covers prices, services, policies and terms and conditions for access to the Western Power network for the next five years. It also details its five year investment plan for the period, which will ensure customers can continue to enjoy a good quality of service while network safety, security and capacity is improved.
